The ears - it's hard to say. Have you taken her temperature? She may be running a fever with allergies. That could be all it is. I suppose you could take a swab to see if there is a build-up of wax in her ears. Be very careful though. You really have to clean their ears well. I recall one person had a groomer come to her home on a regular basis. Her little one ended up with an ear infection. The groomer had not been cleaning her ears.
